Well, there's typically 2 bloomed girls every week (pretty much each time they change the main/rerun events). Whether or not they give a 6* a chace to bloom is random, but they always give at least one 5* bloom status...
but yeah, i'm sure they're quite behind... cause each time DMM does blooming for girls, it's ALWAYS one 6* and THREE 5* girls...
but people forget... Nutaku and DMM are two separate servers... it's the same case with any online game that's spread around the world, servers are gonna do things differently... even if Nutaku is doing things worse than DMM...
Not to sound like an ass, but it pretty much comes down to "be patient and deal with the wait" or "give up on the game and move on", cause all Nutaku support will say is simply "we're sorry, but we'll think about it" and do nothing...
